MAT-GAGE FOR PlCTURE-FRAM ES.

SPECIFICATION forming part of Letters Patent No. 313,197, dated March 3,1885.

Application filed September 3, 1884. (No model.)

To aZZ whom it may concern.-

Be it known that I, EDWARD L. GAYLORD, a citizen of the United States,residing at Bridgeport, in the county of Fair-field and State ofConnecticut, have invented certain new and useful Improvements inMat-Gages for Picture-Frames; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

My invention relates to certain novel and useful improvements inmat-gages for pictureframes, and has for its object to provide a deviceof this description by means of which the corner angle of the mat may beprotracted either from within or from without, and the point ofprotraction determined without recourse to compasses or any means otherthan my device; and with these ends in view my invention consists in thedetails of construction and combination of elements hereinafter fullyand in detail set forth, and then specifically designated by the claims.

In order that those skilled in the art to which my invention appertainsmay more fully'understand its construction and operation, I will proceedto describe the same in detail, referring by letter to the accompanyingdrawings, forming a part of this specification, in which Figure 1represents my device in position upon a picture-mat to determine fromwithout the angle the point of protraction desired; Fig. 2, a centrallongitudinal section of my device and a perspective of one of theflanges; Fig. 3, my device applied to amat to protract the angle thereoffrom within.

Similar letters denote like parts in the several figures of thedrawings.

A is the body of the gage, constructed from thin sheet metal, and havingthe corners C E G thereof right angles. Along the sides B C and D E ofthe gage are flanges F, (see Fig. 2,) projecting downwardly and at rightangles thereto. These flanges terminate at the points B D, respectively.H is a projecting strip formed integral with the body A. Bisecting theangle G, and extending across the body of the device,is a line ofperforations, I, through the metal, and spaced as may be desired fromone another-say one-eighth of an inch. This line of perforations iscontinued to the end of projection H.

The operation of my improvement is as follows: The angle whoseprotraction it is'desired to obtain havingbeen determined and cut, thegage is, if the protraction is to be inward, placed upon the corner ofthe mat (see Fig. 1) and pushed forward until the flanges F rest againstthe edges of the mat. The line of perforations will then bisect thecorner angle of the mat, and the desired point of protraction is thenreadily indicated by a pencil or punch mark made through one of theperforations in the gage. These points having been determined asdescribed at the various corners of the mat, straight lines or cuts mayreadily be made between them. In protracting an angle from withinoutward, as may be sometimes found convenient, the projection H is laidupon the mat, as seen at Fig. 3, and pushed forward until the flangesFrest against the inner edges of the mat. The point of protraction maythen be readily indicated, as before, by means of a mark made throughone of the perforations in the pro jection H.

In my invention I do not wish to be confined to the exact shape orconstruction shown and described, as the gist of my invention rests inthe broad idea of constructing a g for a given angle, whereby it may bereadily and correctly protracted either from within or without.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The gage as described, the same consist ing of a flat sheet of metalhaving an outward projection from one corner thereof, and in the sameplane provided with a line of perforations extending diagonally acrossits face and along the center of the projection, and having upon the twosides contiguous to said projection flanges extending downward and atright angles to the body of the gage, substantially as set forth.
